Panel meter for strain gauge sensors : 2041

The versatile panelmeter 2041 is designed for strain gauge sensors. Strain gauge sensors can be connected with 4 or 6 wires. The 6-wire connection removes the lead wire resistance, as bridge voltage is measured from the sensor poles, and therefore it is recommended for applications requiring very high accuracy. The panelmeter provides 10 V excitation voltage for sensors, max. four 350 ohm sensors. Options to the 2041 include output 0/4-20 mA , 0-10V, 2..4 alarms or serial output RS-485/232.

Display scaling and taring is easy via front panel keys. Scaling can be carried out in two different ways, either by applying the mV values of the bridge or using the teaching function. The teaching is done by first loading the sensors with the min. weight and then with the max. weight, after which the meter will automatically count the scaling. In applications where the sensor loading is not in balance a separate serial connection unit of the sensors
